Simplifying W2 + 2W + -44 = 0 Reorder the terms: -44 + 2W + W2 = 0 Solving -44 + 2W + W2 = 0 Solving for variable 'W'. Begin completing the square. Move the constant term to the right: Add '44' to each side of the equation. -44 + 2W + 44 + W2 = 0 + 44 Reorder the terms: -44 + 44 + 2W + W2 = 0 + 44 Combine like terms: -44 + 44 = 0 0 + 2W + W2 = 0 + 44 2W + W2 = 0 + 44 Combine like terms: 0 + 44 = 44 2W + W2 = 44 The W term is 2W. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2W + 1 + W2 = 44 + 1 Reorder the terms: 1 + 2W + W2 = 44 + 1 Combine like terms: 44 + 1 = 45 1 + 2W + W2 = 45 Factor a perfect square on the left side: (W + 1)(W + 1) = 45 Calculate the square root of the right side: 6.708203933 Break this problem into two subproblems by setting (W + 1) equal to 6.708203933 and -6.708203933.Subproblem 1
W + 1 = 6.708203933 Simplifying W + 1 = 6.708203933 Reorder the terms: 1 + W = 6.708203933 Solving 1 + W = 6.708203933 Solving for variable 'W'. Move all terms containing W to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + W = 6.708203933 + -1 Combine like terms: 1 + -1 = 0 0 + W = 6.708203933 + -1 W = 6.708203933 + -1 Combine like terms: 6.708203933 + -1 = 5.708203933 W = 5.708203933 Simplifying W = 5.708203933Subproblem 2
W + 1 = -6.708203933 Simplifying W + 1 = -6.708203933 Reorder the terms: 1 + W = -6.708203933 Solving 1 + W = -6.708203933 Solving for variable 'W'. Move all terms containing W to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + W = -6.708203933 + -1 Combine like terms: 1 + -1 = 0 0 + W = -6.708203933 + -1 W = -6.708203933 + -1 Combine like terms: -6.708203933 + -1 = -7.708203933 W = -7.708203933 Simplifying W = -7.708203933Solution
The solution to the problem is based on the solutions from the subproblems. W = {5.708203933, -7.708203933}
